Abstract: The invention concerns an electrowetting optical device comprising a chamber (15) comprising first and second immiscible liquids (16, 18) contacting each other at a liquid-liquid interface (19), the first liquid being an insulating liquid and the second liquid being a conducting liquid; a first electrode (20) in the contact with the second liquid; and a second electrode (202) insulated from the first and second liquids by an insulating layer, wherein the second electrode is formed of a conductive molded polymer material, wherein the curvature of said liquid-liquid interface is controllable by application of a voltage between said first and second electrodes.

Abstract: The invention concerns an electrowetting device comprising first and second immiscible fluids, the liquids being sealed within a structure comprising a cap portion, a base portion, a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion, and a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.

Abstract: A lens assembly of variable focal length comprises two transparent plates (24, 38) at least partially facing each other and parallel to one another and delimiting, at least in part, an internal volume (15) containing two non-miscible liquids having different optical indices. The lens comprises an elastic element (36) capable of deforming in response to a change in pressure of the liquids, in such a way as to substantially maintain the optical properties of the lens assembly, e.g., in order to maintain the parallelism of the two transparent plates.
